I don't know where he got the energy from," Bruintjies said yesterday at their Tuks club.Also, there were long-jumper Luvo Manyonga, sprinter Carina Horn and 400m hurdler Wenda Nel, all of whom have already achieved qualifying times for the 2016 Rio Olympics.Club manager Danie Cornelius pointed out that Tuks had four athletes currently ranked No1 in the world: Simbine, Horn, Manyonga and pole-vaulter Eben Beukes.Bruintjies made it clear he had no ambition to go fast just yet.
